There are a lot of knockoffs out there, but we bought a
couple of the original Skychairs and hung them over a
limestone drop in our creek from the limbs of an
overhanging oak tree. These are hands down the most
comfortable chairs (and footstools) we own, fully
adjustable for comfort. I could easily sleep in it if I
wanted to. I am seriously thinking about putting up some
kind of repeater for my WiFi so I can get a connection
from one! It would be like working from a treehouse. They
come in oiled canvas for hanging on porches and a
synthetic that is weatherproof and doesn't retain
rainwater (what we have). They are very well-built and
look as good as new after three years of use and we use
them every day. I'll see if I can find some pics to put up
on my blog.
